Starts with a opening brace and ends with a opening brace.
In our example, we have taken two objects.
p1 and p2 are keys. It’s values are present inside opening and closing brace.
Each object has name, age and company info.

Once the user clicks on the button, we invoke $.getJSON method.
First parameter we are passing is the URL of the json file. Next the call back function.

The call back function receives the jSON data which we have called as obj in our example.
Using $.each() method we iterate through all the objects present in our json file and then split them into key => value pair.

Now using the value we fetch the name present inside each objects value.

jSON & Database
We can generate jSON data out of a database and then fetch it using jQuery and display it on our web browser without the need for the modification of any code.
Whenever the json file or the database table data gets updated/modified, it instantly reflects on our web application.

Note:
You must open the file from a server. localhost works file too.
If you access the files directly from your computer folder, this application doesn’t work. So the files MUST be on a server.
